Buying Guide

Choosing only one or two of the above mountain bikes under $300 can be a challenge. However, we’ve provided an easy-to-follow buying guide for the best mountain bikes under 300 dollars below, listing the most common and important features to bear in mind. With this information, you can narrow down your choice to select the mountain bike that’s closest to having these features. 

Wheel Size

There are two-wheel sizes to consider: height and width. For beginners, these dimensions will be listed with the product as 26″ x 2.2″. The wider the tire, the easier it will be to cycle through mud, rain, and snow. This is ideal for biking on off-road trials and not feeling restricted in these circumstances.

Also, you should consider the tire’s height. A common size is 27.5 inches. Due to the bike’s smaller size, it’ll steer and accelerate easier than other tires, making the bike more responsive and easier to control and move on off-road trails. Furthermore, the bike is lighter due to this smaller size, helping you to comfortably cycle up hills and accelerate easily.

Alternatively, 29-inch wheels are easier to roll over tree trunks, rocks, and bumps along your route. The larger diameter makes the bike easier to ride over technical terrain and you can cruise over seemingly-impossible environments with less effort. Also, the higher air volume provides additional suspension, contributing to a smoother and more enjoyable ride.

There are two types of suspension to consider for a mountain bike: hardtail and full suspension. If you’re looking for a simple, lightweight option, a front suspension system makes a great contender. This suspension type is easier to control and cheaper to maintain as it doesn’t come with any moving parts, such as bushing, pivots, and more.

Furthermore, without having a rear suspension system, too, a hardtail bike reduces the chances of you making errors on technical terrain and causes you to think more about your body position, rather than relying on the bike to put in all the work.

On the other hand, a bike will perform at its best with a full suspension system. By allowing the cycle to take some of the pressure off of you while you ride, you can focus more on the ride rather than stress thinking about the terrain and your body posture. In fact, full-suspension can give you more handling power in technical terrain than a hardtail bike ever could. Furthermore, you’ll encounter more confidence as you ride on off-road trails and challenging routes. For that reason, this is a great mountain bike under 300 bucks!

Frame Material

There are many materials to consider with your bike’s frame, with the two most popular options being aluminum and steel. The latter is ideal if you’re a cyclist on a budget or don’t intend to use your mountain bike that much. Steel is significantly stronger than other frame materials and can absorb more blows when suffering damage.

However, steel is heavier than aluminum, making cycling more challenging since you have to fight through this excess weight. Steel is also not resistant to corrosion, so it can impact the bike’s well-being if not properly cared for.

Alternatively, we recommend a bike with an aluminum frame. This material absorbs more shocks and vibrations as you ride, helping to improve the overall comfort and enjoyment of cycling. Another great advantage of an aluminum frame is its lightweight, which allows you to accelerate easier and maintain a high speed when cycling. Furthermore, an aluminum frame isn’t prone to rust or corrosion, which means it’s a more suitable material to use when it’s raining.

The Gears

You might be wondering how many gears you need on your hardtail mountain bike and the number is completely dependent on the environment you’ll be riding or your preferences when cycling. For example, if you want to make mountain biking more challenging.

Most importantly, the number of gears is dependent on the environment. For example, if you plan on cycling up hills, you won’t need a wide range of gears, but you will as you head back down the hill. Otherwise, you’ll end up heading down a steep hill at full speed with a less chance of coming to a stop. For these scenarios, we recommend a hardtail mountain bike with up to 17-21 speeds.

On the other hand, if you’ll only ride your mountain bike on smooth surfaces (although, a mountain bike is designed for difficult terrain), fewer gears will suffice—such as up to four gears.

Brake Type

Another feature to carefully consider is the hardtail mountain bike’s disc brake type: mechanical or hydraulic disc brakes. Mechanical disc brakes are designed simply and easy to use. They’re also inexpensive, which is great if you’re on a budget. In fact, they’re ideal if you’re a beginner or entry-level cyclist.

However, mechanical disc brakes can be difficult to maintain and easily damaged, lending to time and money spent on repairs. They also require a lot of pressure to bring the bike to a stop and aren’t always as responsive or sensitive as the alternative.

On the other hand, hydraulic disc brakes are smoother and more responsive, allowing a more impressive stopping power. Therefore, you can confidently use this braking system in rain, snow, and muddy conditions with ease. Plus, you don’t have to apply as much force. However, for these incredible features, these mountain bikes will be more expensive and difficult to adjust and maintain, making them unsuitable if you’re on a tight budget.


Finally, no-one wants a heavy, bulky mountain bike that makes it difficult to ride and transport. Generally speaking, the heavier the bike, the more challenging it will be to cycle and reach top speeds. The average weight of a mountain bike is between 28 and 32 pounds, although, your chosen weight depends on your personal preferences and riding style.

Lighter bikes, be it mountain bikes or other models are easier to maneuver and get started and turn around corners, while also being easier to bring to a stop. Furthermore, lighter also makes it easier to climb tough hills as you don’t have as much weight to lift up the hill.

Several factors can affect a mountain bike’s weight, such as the suspension system. A hardtail suspension is lighter since there are fewer materials and components on the bike. Furthermore, the fame material also influences the bike’s weight. For example, steel is much heavier than carbon fiber.

Who is a Mountain Bike Designed For?

Mountain bikes are designed for riding on mountain trails, fire roads, and unpaved surfaces. Although they can be ridden on smooth pavements, the majority of their time is spent on off-road conditions and some of the toughest terrains you’ll experience.

To comfortably and safely ride in such conditions, a mountain bike must come with a range of features, including a suspension system (this can be full or hardtail). A full-suspension mountain bike is ideal for riding in off-road conditions. This suspension type can provide an array of comfort for days and is well-suited if you suffer from knee or back pain. In fact, this added bounce means that you’ll receive less traction during challenging climbs, where you’d usually become out of breath or slower. 

Due to these conditions, the disc brakes on mountain bikes are much more reliable than other bike types. In fact, these disc brakes make the bike better at coping with dirt and grim, where it’d ordinarily get clogged up.

There are many important features to consider with a mountain bike (as mentioned in the section earlier). With these considerations, a mountain bike isn’t designed for beginners, but those who have experience in cycling and are confident and excited about the concept of riding in some of the most off-road conditions. 

Where To Buy a Mountain Bike?

Thankfully, there are many places you can purchase a mountain bike that’s high-quality and comes with many features. One of the most significant things to consider is the brand. You should purchase mountain bikes from a reputable supplier with years of experience to give you peace of mind that it’ll be long-lasting and high-performing. Such brands include: Mongoose, Huffy, Northwoods, and more. 

Many online retailers, such as Amazon, allow you to make a purchase of the best mountain bike under 300 dollars without leaving your home. But for your own peace of mind and to avoid any delays or errors, we recommend examining the size guide in the bike’s listing and ensure that the measurements are appropriate for your height.

What Size Do You Need?

Choosing the right size frame for you is important to ensure that you’re safe during your time on the mountain bikes. In order to make your purchase, you may need to take some measurements of yourself (or the person you’re buying the bike for). 

Here’s an outline of some of the most popular sizes and the frame size of the best mountain bikes under 300 dollars you’ll need:

  • Height: 5′.0″. Frame Size: 15”
  • Height: 5′.3. Frame Size: 16”
  • Height: 5′.7″. Frame Size: 17”
  • Height: 5′.9. Frame Size: 18”
  • Height: 5′.11″. Frame Size: 19”
  • Height: 6′.2″. Frame Size: 20”
  • Height:  6′.5″. Frame Size: 21”

In many cases, your height won’t be exactly any of these figures. Therefore, you’re stuck with wondering which size is best for you. Consider the reach—a term for how long the bike feels when you’re in the riding position. This is influenced by the length of your upper body as opposed to your height.

If your trunk length is longer than average (compared to your height), then we recommend choosing the largest option of the two sizes that you’re stuck between. Alternatively, if your reach is smaller than the average size, opt for the smaller frame. This factor is important as it prevents you from stretching your legs to reach the floor when you’re in the riding position.

The Runner’s Up

We hope you enjoyed these mountain bikes under $300 reviews. But if you’re still unsure of the best mountain bike(s) for you, the Huffy Hardtail Mountain Trail makes an excellent runner-up. It features 21 speeds for versatility and practicality in adventurous rides and can even handle exposure to mud, rain, and snow. The feature of providing great traction on wet and muddy surfaces of these mountain bikes makes it the ideal bike for hilly terrain.

This mountain bike handles well, thanks to the 27.5-inch wheels that make it easier to control and steer around tight corners. Meanwhile, the aluminum frame minimizes shocks and keeps the bike lightweight, so you can travel far and fast without anything holding you back.

Alternatively, the Mongoose Status 2.2 Mountain Bike is ideal for those on a budget (you can also give a look to the mongoose mech mountain bike model). It features wide, knobby tires to keep you secure to the ground, even when it’s muddy or you’re cycling over tree trunks. Plus, the aluminum frame reduces the amount of shocks you feel and adds plenty of durability, while reducing maintenance.
